IMPROVEMENT IN LARD-PRESSES.

Specification forming part of Letters Patent No- 179,6l5, dated July 4,1876; application filed April 6, 1876. i

To all whom it may concern:

Be it known that I, CHARLES J OHN SCHIL- LER, of the city of Baltimore,in the State of Maryland, have invented certain new and usefulImprovements in Presses for Lard and' other Articles and I do herebydeclare that the following is a full, clear, and 'exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to theletters of reference marked thereon,which form a part of this specification.

My invention relates to presses forlard and other articles to thepressing of which it is adaptable; and consists in certain improvementsin the construction of the same, as hereinafter more fully shown anddescribed. In the accompanying drawing, forming a part of thisspecification, Figure l is a plan view of my improved press. Fig.2 is afront elevation of the same. Fig. 3is a vertical section. Fig. 4 showsthe clamp indicated by U, herein detached. Fig. 5 is a sectional view ofthe hand-wheel and worm-wheel herein described, and marked,respectively, G and B.

In the saiddrawing, A designates a worm, formed upon a shaft, F, havingbearings D and K on the top of the construction, said shaft F beingprovided with the power-wheel O. B indicates a gear-wheel, which engageswith the worm A, and immediately above wheel B is placed the hand wheelG, as. shown. The cross-beam M rests upon t-hesupports 0, connected withthe body of the press P, the whole being supported by the legs Q. Thesaid cross-beam is provided with a nut, N, and has an aperture throughthe center for the passage of the vertical screw H, with which the saidnut N engages.

As shown in the drawing, the screw H also passes through apertures inthe worm-wheel B and hand-wheel Gr, connection being es-' tablishedbetween the screw and said wheels by means of the gib or key I, placedin the keyseat g, Fig. 5, formed within the said two. wheels, said keyprojecting into the keyway J, formedin screw H, and extending from endto end thereof, as shown in Fig. 2.

The clamp U is made in two parts, as shown in Fig. 4., the same beingbolted to the crossbeam M, and formed to enter the groove m in wheel B,so that the wheels B and G, being combined by the key I, are held inposition by the said clamp, which prevents their being displaced by thescrew H in its movement. Thus the screw H is allowed to pass freelythrough wheels B and G, and engages only with the nut N in its passagethrough the cross-beam.

is a valuable addition, as the power of the press is greatly increasedby the use of the lever in operating the screw H, through the worm A andwheel B. The bearing D ofsaid shaft F is usually made twice as long asthe worm A, to allow the latter to be turned out of gear from worm-wheelB, this being effected by reversing the movement of wheel (J. The saidhearing has within it a steel plate, 0, against which the shaft Fpresses, the end of the shaft being also of steel. R is the pressplate,which is coupled to the screw H at its lower extremity, thepl'essingsurface of said plate being provided with pins 1", which assistin the withdrawing of the crackling or mass from the basket after theoperation of pressing.

In Fig. 2 is shown the crackling or mass, (indicated by 'S,) clinging tothepress-plate as it is being raised from the basket, and thiswithdrawing of the mass is very important in the pressing of lard or oilcake, as it saves a great deal of labor. The basket T, of metal or anysuitablematerial, is made in two halves, hinged together at c, andcoupled together at d by the fastening device shown in Fig. 2. Saidfastening consists of the pieces at and d. pivoted at 0, to one part ofthe basket, and connected by the upright piece f. The said pieces 61 andd are made to close on the pins 8, fixed to the other half of thebasket, and

The worm shaft F is provided with a ratchet attachment and lever, L,which the plate R by means of a swivel-joint, as shown in the drawing,the clamping part m being made in two parts, and bolted to thepress-plate, so that the screw is turned without turning thepress-plate. Within a recess in the press plate receiving the lowerextremity of the screw, as shown, is placed a steel plate, V, the end ofthe screw pressing against it being of the same material. The nut N maybe made solid with the cross-beam M, or it may be made detachable, asshown in the drawing, so that it may be renewed when worn.

It will be observed that the screw H may be rapidly operated by means ofthe handwheel G only, the Worm A being out of gear, and the power may begreatly increased by using the worm shat't, provided with handwheel (1,and ratchet and lever L.

Having described my invention, I claim-'- 1. The combination of thehand-wheel Gr, worm-wheel B, gib I, clamp U, and screw H, as set forth.

2. In combination with screw H and wheel B, keyed as shown, theworm-shaft F, having the worm A thereon, and provided with handwheel (J,as shown.

3. In a press, the combination of wheel B and the worm-shaft in thebearings D and F,

said shaft being provided with hand-Wheel C, and ratchet and lever L, asspecified.

4. The pressing-screw H, provided With the keyway J, in combination withthe Wheels G and B and gib I, as described.

5. The screw H and press-plate R, the iatter being coupled to the screw,as shown, and provided with the projections rfas set forth.

6. The basket T of the press, the two parts being hinged and coupledtogether, provided with the removable perforated plate a, as shown.

7. The press-basket T, the two parts being hinged together, and alsoprovided with the fastening worked by the handle a andconnecting-pieeef, as shown and described.

8. In a press, the combination of the basket T, made in two parts,coupled together, and provided with plate a, the grate-bars b, and thefountain W, as shown, for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

CHARLES JOHN SCHILLER.
